That's not really a consideration: the partial pipes are always tuned in
pure ratios to the main pipes as their function is for tone color rather
than harmonic.

Well, yes.  Chromatic unisonoric ones in particular.  It would be tricky
to tune to the beating of a tone on the push with a tone on the draw...

Diatonic/bisonoric accordions are a dark art of its own.
